Well, just some general reflections on the Physics Exam
First of all, I managed to score 159/180 - Scraping an A+
ie. 79.5/90
Funnily enough, I got 5 Questions on Further Electronics Wrong ( -10 Marks)
And I lost half a mark on explaining modulation (-0.5 Marks)
Although, this makes me wonder if I was lucky and I got two awesome examiners, I could have easily got an 80/90! D:
But the Further Electronics detailed study really does annoy me, as I think that we and the people doing Relativity really got dudded in terms of how difficult our detailed study was compared to Materials and Structures, which many of my friends as well as my teacher, said was VERY easy!
And to add salt to the wound, VCAA doesn't standardise Detailed Studies.
IMO, its really becoming a game of predicting the easiest detailed study, so if I were a physics teacher, I'd be picking F.E or Relativity next year, because it's likely it'll be easy next year!
Does everyone also agree on this unfairness?
-
Most people would believe that S&M is in general the "easiest" detailed study to choose from. But I agree, there should be some form of standardisation to level the playing ground. By the way, when did you order your statement?

Well there are some years where people say that S&M is harder than Further Electronics, but either way, its not fair that they don't standardise it, but I think we should scrap this whole detailed study stuff and just all do the same course, cause the point of the detailed study is for students to choose an area that interests them, but schools choose it anyway, so its pointless.
Even if it were standardised, we'd still have complainers!
I ordered my statement late last week, so last Thursday-ish
-
Firstly, congrats on the great score! :)
to Materials and Structures, which many of my friends as well as my teacher, said was VERY easy!
And to add salt to the wound, VCAA doesn't standardise Detailed Studies.
My whole school did s&m, and I don't think I heard anyone say it was easy.
-
It is probably the easiest detail study out of all, but not necessarily easy in itself
-
My whole school did s&m, and I don't think I heard anyone say it was easy.
Like Graphite said, its not necessarily easy, but compared to further electronics and relativity, it was relatively easy
It's like saying Methods isn't easy, but compared to Specialist Maths, it is quite easy!
Either way though, there was definitely a discrepancy with the difficulty of the detailed studies

Well stated. Still awaiting my Statement, but my A+ will likely be close to yours, due to Further Electronics. I guess our chances of a 45+ score in physics is looking unlikely. All we can do is hope the end-of-year exam is incredibly difficult. :P
By the way pi, are you ordering a Statement too?

Nah. I roughly know how well/badly I did in each section and its not really as if I could change anything. And to be honest, I'm just happy to have gotten an A+ in the first place, knowing how low it is wouldn't do much good to my confidence.
I would only order it if I thought I 'beasted' the exam, or got a score that I felt was considerably lower than my prediction (eg. If I had got a B in my results sheet).

why thankyou "luffy" :P
"luffy" reminds me of your brother :P
LOL! nah, 45 is still possible
BUT! i hope that the end of year exam is very difficult and also that they make sound very difficult so that 92% of the state is screwed (:
(cause im not gonna do sound, photonics ftw)! :D
then the 2% of the state that do photonics get their day in the sun ;)

I'm joking around, if it were up to me, i'd like to see everyone do equally well, but considering that I got screwed by Further Electronics, I just want some consolation :D
Nothing Personal :P

45 is only possible if you get 100% or extremely close to, on the end of year

84/90 :D
Lost some unexpected marks but still pretty thrilled

yeahh i know, but its still in the realms of possibility :P
that's why i want a particularly hard exam! :)
-
Aim high and if you don't succed, you won't fall as far. Just having a positive attitude and positive thinking already gets you ahead of most of the rest of the people doing the exam.
-
If only I knew that earlier ^

Friend of mine managed 88.5/90 in the exam.
-
Why am I doing 6 subjects in year 12? I've been wondering the same thing myself...:P
-
First of all, I managed to score 159/180 - Scraping an A+
well done son, i always believed in you, now go and continue making me proud in unit 4.
and no, i dont think the unfairness is fair, but, such is life.

Thushan, did you order your statement of marks? If so, how did you go?

Yup I did. Still waiting. But as far as I know, absolute max for physics is 88/90, for chem absolute max is 70/72.
-

Wow, the absolute max of physics was 88 and chem was 70? I find that a little surprising for physics; I personally thought the exam was relatively straightforward, other than the detailed studies (further electronics for me) and I'm sure there are people out there who would have got 100% on their respective detailed studies.
-
Oh whoops, you misunderstood me, i meant the absolute max that I could have gotten for physics was 88 (i dropped 2 marks on a MCQ) and for chem absolute max I could have gotten was 70 (dropped the IR MC and a mark on the first extended response).
-

Ahhh - no wonder haha. My bad for the misinterpretation.
88/90 and a 70/72 are still very high scores! Nice work! I wouldn't worry about the IR question - a large portion of the state would have gotten it wrong with you :D (myself included)
-
Ahahah yeah 20% got that one right.

LOL! i was expecting a 70 in chem as well, cause i got 2 MC wrong, but i cant believe i lost so many marks for explanations, like freakin fractional distillation!! annoyed =.=
and btw guys, im expecting that some people would have got 90/90, theres always a few every year, mind you i only lost half a mark on core, damnn further electronics!!!
-
Ahahah yeah 20% got that one right.
and you are not in that 20%, hence you are looking at an ATAR of <80
-
damn you
-

but youre assuming that everyone else who did vce got everything thushan got correct, correct as well :P
-
Got 86/90. Somewhat happy with it, but I guess careless mistakes and a lack of studying didn't help.
In AOS1Q20 got 2.5/3, got 0.5/2 for ElecQ9 (I am aware why I lost the marks but I still maintain that my ans is also correct, but who cares), and lost the springboard MCQ.

im guessing you drew sharp points rather than curved points for question 9?
but hmm, congrats on the score :)
-
other way, i drew curved points
-

I just had a look at the physics exam again.
Just out of curiosity, whats your reasoning behind the curved points?
-
P(diode)
= V(diode)I(diode)
= V(diode)I(circuit)
= V(diode) x V(r1 + r2)/(R(r1) + R(r2)) --> where V(r1+r2) is the total voltage drop across resistors R1 and R2
Given V(diode) is constant and V(r1+r2) is constant as well, we get
P(diode) = a/(b+R(r1)) where a and b are constants
So P and R(r1) do not have a linear relationship -> it's a hyperbola, so as R(r1) increases and decreases, P follows a hyperbolic characteristic, increasing and decreasing in that kind of fashion.
Showed my physics teacher (assessor) who agreed with my reasoning. Doesn't matter now though, I don't mind.

Ok, now you're getting me worried. I remember having curved, hyperbolic lines in my exam! Were the lines supposed to be straight? I had distinct sharp points at the 1,3,5 seconds though.... Do you reckon they will pay me the mark? T_T Wait a minute, isn't the "curved" answer "more" correct than the others? :'(
*sigh* Even more eager to see my statements now...
Also, Thushan, you forgot to mention R(LED) and V(LED) when substituting for I(Circuit). However, as R(LED) approaches 0 and V(LED) is constant, it won't make a difference to your answer.... As if VCAA assessors didn't see this when creating their own worked solutions...
-
lol, further amazement of myself getting an A+, I drew curved lines too :o
Out of curiosity thushan, what is your definition of 'lack of studying'?
-
Also, Thushan, you forgot to mention R(LED) and V(LED) when substituting for I(Circuit).
Yeah, that was implied. V(LED) is constant and R(LED) is irrelevant in the calculation as I am effectively considering the two resistors r1 and r2 as one resistor and measuring the current and voltage through them.
-
other way, i drew curved points
oh right, i drew sharp points for that and got full marks :D

hmm, well, technically yes, the graph of the current versus time graph, will be a hyperbola, hence so will the power versus time
but youve also got to consider that the brightness against power graph is not linear either
in fact, here it is http://www.flickr.com/photos/therontrowbridge/5322251604/
that function to me looks quite hyperbolic, so using composite functions, yes, the brightness versus time should be a linear graph
but hmm, sharp points are technically right :) so you should get a mark i guess
also to back up my point, its a composite of a positive and negative hyperbola, which means you should end up with a line of opposite gradient (:
-
Ah, that's fair enough. I ended up getting 0.5/2 for that question.
-

i guess that 0.5 does show that even the examiners arent quite clear where to award marks :P
-
Just got mine: 87.5/90. Very stoked!
-
Just looking through it now: Question 20 for Motion, it says I got 3/6 but looking at the actual exams it was only a three mark question.... Same for question 12 in electronics: it says I got 2/4 but the exam says it's only a 2 mark question. What's that about???
-
The exam is marked by 2 examiners. Thats why the total score is 180 and not 90.
congrats on the awesome score btw ;D

Dude I only got 2 more makes than you. Don't worry your grade means nothing. It's your ranking and that's based off your score. You can still get 40+ man! But yea i've pretty much given up on physics too. Bottom 2 for sure.

Yeah I lost the dumbest mark ever. I got 1/6 for the super easy motion question (Q11) about calculating her apparent weight at the bottom of the circle. I learnt from my mistake though. Always set aside time to double check your paper! I just realised half of the marks I lost would have been avoided if I didn't spend 30 minutes thinking of that stupid block question (Q7) (which I didn't change my answer and got full marks for anyway) and use that time to double check! 30 minutes!
Must be an MHS thing, I've also given up :)
Yea probs. I heard that the highest mark at MHS is like some guy that lost 3 marks. I know a couple of Macrob girls that got better than this and I think one's in Year 11. Kind of makes us feel shit considering Physics is suppose to be a subject that guys are good at. Hopefully we did better in Chemistry :P

That bloody block question... Thought it was too easy and spent like 15 mins on it.

i liked that block question, it was quite easy if you've gone through the mechanics chapter in specialist maths, i dont think they teach you how to work with forces properly in physics

is a 50 still in sight for me if i got 85/90 and almost 100 in sacs. provided i get very high in end of year?

100 percent on exam. then yes.
otherwise probably 48 49

so can't afford to mess up end of year!
-

it's in sight, but it could depend on how the end of year exams turn out, ideally, if the end of year exams are HARD, you'll end up beating back those who beat you here, so you have the chance for a 50, but if the end of year exams turn out easy, and most of the people who beat you are able to equal you, you'll end up with a 45+ study score, but not a 50 (:
-

To be very, very blunt, even if you get 100% on the end of year exam, it's incredibly unlikely - it'd have to be a very difficult exam. I've heard of people losing 3 or so marks in a moderately difficult year; I think -1 was the limit in my year. If it's an average exam, you're probably looking at high 40s, and if it's an easy exam, you might be looking at mid 40s... even with 100%.
-
Ahk. What about an 86? Given A+ was 78/90?
(LOL got jibbed on one qn according to physics examiner teacher - but we already discussed this)
-
i still think the a+ cutoff was extremely low this year, meaning hard exam, hopefully end of year is just as hard then

Gahh, got 77/90 1 mark off A+, pissed off cause i know i should of gotten A+, stuffed up 5 questions in multiple choice... paniced at the end.
anyway, if my sacs are like within the top 4 of my school (95%+) what score would i roughly need at the end of year to get low 40's? any guesses? im really stressed..

it depends on the strength of your cohort
considering that you go to dandy, you have quite an average-strong cohort compared to many other schools in victoria
to get above 40, you'll really need to get a high A+ for the end of year exam, so im guessing 86+/90
-
no one got 90/90. Chief examiner teaches at my school. He said that the highest was 89.5 or something
